My barber doesn't really have a set price...all depends on what you're getting done. Simple edge-ups are $15 for hair and beard but he can go up to $50 if you are getting those Bigen or Black Ice treatments or getting shampoo/conditioner combo for hair and facial hair.
If young breh has that level of demand, he should charge whatever works for him. $50 sounds like a lot but if your chair is always full, then it's the right price. If he went down to $35, the demand might be too great and he wouldn't be able to see everyone anyway. On top of that, if his schedule is crowded to the brim, breh might have to raise prices just a little bit more...gotta be careful with that though.
